Answer: Employ API Gateway's canary release feature to gradually route a set percentage of traffic to the new API version.
The correct answer is D. Canary deployments allow developers to gradually roll out changes to a small percentage of users, which helps in testing the new version in a real-world environment without fully replacing the existing version. This approach minimizes risk and ensures any issues can be detected and addressed before a full rollout. Utilizing API Gateway's canary release feature, you can direct a specified percentage of traffic to the new API version using the canarySettings setting, making it the simplest and safest solution for rolling out the changes to a limited number of users.
